Some days it seems that there is little good left in the world, as we're bombarded by so much of the bad, but if you look for it, you will find plenty of good out there too.

John Smith, a 91-year-old widower, has dedicated nearly 20 years of his life to helping homeless animals in Baltimore, Maryland. While he may not have the energy that he once had, he manages to find time when it comes to providing love and affection to creatures who aren't lucky enough to have a forever home.


It all started when Smith really missed having a dog around, and because his wife didn't want one, he began visiting homeless animals that were living at the Maryland SPCA in Baltimore.

Then, he took it a step further by becoming an annual participant in the March for the Animals. Taking place in April each year at Druid Hill Park, the 1.5-mile walk benefits animals that are in the shelter.

His daughter, Jenny Powers, told ABC that her dad has always loved dogs but didn't always have them around.

"My dad was not allowed to have dogs. My mother did not want a dog in the house," she said.

Smith's compassion rubbed off on his daughter - she will be right by his side during this year's march. To date, Smith has participated in 18 of the events benefiting the Maryland SPCA as one of its long-time participants.

And, now that he's moved into a retirement home, he has his own beloved dogs, Fred and Ginger, at his side.

In the video below, you'll see more about him, and how he's making a different in the lives of our furry four-legged friends.
